2 Esdras 4:1–4
4 Then the angel that had been sent to me, whose name was Uriel, answered 2 and said to me, “Your understanding has utterly failed regarding this world, and do you think you can comprehend the way of the Most High?” 3 Then I said, “Yes, my lord.” And he replied to me, “I have been sent to show you three ways, and to put before you three problems. 4 If you can solve one of them for me, then I will show you the way you desire to see, and will teach you why the heart is evil.”
